, by original designation.
Diagnosis.
Valim & Palma (2015)
compared this genus with
Brueelia
s. str.
, “
Brueelia
s. lat.
” (=
Priceiella
n. subgen.
),
Corvonirmus
, and
Turdinirmus
. We refer to their description for details on how to separate
Melibrueelia
from these genera. For a comparison with
Nemuus
n. gen.
, see the diagnosis for this genus above.
Description.
Both sexes
. Head pentagonal, wider in male than in female (
Valim & Palma 2015: fig. 2
). Marginal caina interrupted laterally and submedianly, no displaced section at osculum. Frons hyaline. Dorsal preantennal suture continuous with hyaline margin, reaching
ads
and
dsms
, and completely separating dorsal anterior plate from main head plate. Ventral carina not continuous with marginal carina. Ventral anterior plate present, crescent-shaped. Coni small, slender. Antennae sexually dimorphic, with male scapes more than twice as long and twice as wide as female scapes, and more distal segments modified as in
Valim & Palma (2015: fig. 2
A
)
. Head setae as in
Valim & Palma (2015: fig. 2)
;
as3
absent;
pns
present, sensilliform;
pos
on marginal temporal carina. Temporal carinae not visible;
mts
3
only macrosetae. Gular plate broadly triangular.
Prothorax rectangular (
Valim & Palma 2015: fig. 1
);
ppss
on postero-lateral corners. Proepimera oblique, moderate, curled around coxae II. Pterothorax pentagonal: lateral margins highly divergent, posterior margin convergent to slight median rounded point;
mms
moderately (in males) or widely (in females) separated medianly. Meso- and metathorax not fused, each with 1 seta on postero-lateral corner on each side. Let chaetotaxy as in
Fig. 25
, except
fI-p2
absent;
fI-p3
ventral, submarginal, thorn-like.
Abdomen rounded in male, more oblong in female (
Valim & Palma 2015: fig. 1
). Abdominal chaetotaxy as in
Table 2
. Tergopleurites II–XI in male and II–VIII in female narrowly divided medianly; tergopleurites roughly triangular in male but roughly rectangular in female. Tergopleurites IX+X and XI fused in female. Sternal plates rectangular, broad, but not approaching lateral margins of abdomen; sternal plates very slender in male. Pleural incrassations slender. Ventral section of tergopleurites very narrow. Re-entrant heads slight, blunt.
Male
subgenital plate roughly trapezoidal, with anterior margin rounded, posterior end reaching terminal end of abdomen and there often widening slightly. Female subgenital plate rounded triangular, reaching vulval margin and there flaring into broad cross-pieces (
Valim & Palma 2015: fig. 1B
); plate with conspicuous reticulation. Vulval margin gently rounded, but median section concave; lateral to concave section vulval margin is thickened. Slender
vms
and thornlike
vss
;
vos
follow lateral margins of subgenital plate, with distal
vos
median to
vss
.
Basal apodeme (
Valim & Palma 2015: fig. 1C
) rounded trapezoidal, anterior end slightly wider than posterior end. Proximal mesosome slender, widening in proximal end. Mesosomal lobes slender, fused and extended somewhat distally. Ventral surface with large rugose area surrounding ventrally located gonopore; 3
ames
microsetae on each side antero-lateral to gonopore; 2
pmes
microsetae on each side, on lateral margins posterolateral to gonopore (not illustrated by
Valim & Palma 2015
). Parameral heads folded medianly, rectangular. Parameral blades connected to parameral heads by slender neck, bulging in mid-section, and tapering distally;
pst1–2
sensilla, central, near distal end of parameres.
Host
distribution.
Only known from
New Zealand
honeyeaters (
Meliphagidae
).
Geographical range.
New Zealand.
Remarks.
We do not include illustrations or a description of
Melibrueelia novaeseelandiae
—the
type
and only species of the genus—because it was recently described and well illustrated by
Valim & Palma (2015)
.
No
representative of
Melibrueelia
was included in the phylogeny of Bush
et al
. (2016).
